The NS2 series AC motor starter is a multifunctional electrical device that integrates isolation, protection, and control functions. Specifically designed for the safe operation of three-phase squirrel-cage asynchronous motors, it is widely suitable for industrial and commercial power distribution applications. With a rated voltage up to 690V and a current range from 0.1A to 80A, it offers shell frame ratings such as 32A and 80A to meet the adaptation requirements of motors with varying power levels. Additionally, it complies with international and domestic authoritative standards including IEC 60947-2 and GB/T 14048.4, ensuring reliable performance compliance.
In terms of core functionality, this series of starters incorporates a modular design with multiple protections. Short-circuit protection is achieved through an instantaneous electromagnetic trip mechanism, where the iron core can immediately cut off the circuit when the current reaches the set value. Overload protection relies on the thermal effect of a bimetallic strip, combined with temperature compensation, ensuring stable response in environments ranging from -5°C to +40°C. For common motor faults, the differential mechanism amplifies the current imbalance signal during phase loss, rapidly triggering the trip to comprehensively prevent motor damage risks. Additionally, it integrates power distribution line protection and infrequent load transfer functions, and can also serve as an isolator, delivering the "one device, multiple functions" application value.
The NS2 is a compact motor starter integrating three core functions: overload protection, short-circuit protection, and isolation breaking, specially designed for direct starting scenarios of three-phase induction motors, with a rated voltage range of AC 230V~690V and a rated current range of 0.1A~80A. Adopting a modular structure, this product can be directly installed in power distribution cabinets or beside motors, with both manual and electric operation modes. It achieves precise protection through the thermal-magnetic tripping principle, can effectively cut off motor overload and short-circuit fault currents, isolate live circuits to ensure maintenance safety, and is widely used in motor control circuits of industrial equipment such as fans, water pumps, and conveyors.
With the core advantages of function integration, precise protection, and convenient installation, this product is mainly suitable for industrial scenarios of direct starting of three-phase induction motors: ① General industrial equipment: Motor control of fans, water pumps, air compressors, conveyors, mixers and other equipment to achieve overload, short-circuit protection and isolation; ② Construction machinery equipment: Motor starting of small winches, elevators, and ventilation equipment, adapted to the compact installation needs of construction site power distribution cabinets; ③ HVAC systems: Motor control of central air-conditioning chilled water pumps and cooling tower fans, supporting remote start-stop and adapted to building intelligent control; ④ Agricultural irrigation equipment: Motor starting of water pumps and irrigation units, withstanding the environmental characteristics of large outdoor temperature differences; ⑤ Light industry production lines: Motor control of food packaging machines, textile machinery, and printing equipment, with modular design facilitating rapid transformation of production lines; ⑥ Small power distribution systems: Motor protection in workshop power distribution cabinets and distribution boxes, replacing split combinations and saving cabinet space.
